The song quickly topped various digital music charts within 10 minutes of release. Moreover, the song reached #1 on Gaon Music Chart.

### Japanese version

The single was announced with no confirmation of title tracks, however fans were allowed to pre-order the regular, and limited editions of the single.

## Music video
### Korean version

The group worked with long-time collaborator Rino Nakasone Razalan, whom they had previously worked on for the group's previous single, "Tell Me Your Wish (Genie)" on the choreography for "Oh!", and director Cheo Soo-hyun. A teaser video was released to various websites on January 23, 2010, causing at least one of them – Naver – to be overwhelmed by high visitor traffic. The full video was released on January 26, 2010. Eventually, the dance version of "Oh!" was released on S.M. Entertainment's YouTube channel. As of December 2016, the song's official music video has attracted over 100 million views on YouTube, becoming the group's fifth music video to do so following "Gee", "I Got A Boy", "The Boys", and "Mr. Taxi".
The girls wear specific numbers in the music video; each number was personally chosen by the members. In the story version, it is shown that they were cheerleaders for an American football team. In the middle of the video, Sooyoung mishandles an American football helmet (turns out to be a University of Iowa Hawkeyes football helmet from the Big Ten Conference) causing the computer monitor to be damaged. At the end of the video, the girls meet the Black SoShi, their malevolent selves from a parallel universe. (It's later revealed through their "Run Devil Run" story video that the Black SoShi emerged from inside the monitor after it was struck by the helmet.)

### Japanese version

The Japanese version of "Oh!" was released on September 14, 2012. A dance version for "Oh!" was released on September 18, 2012. The "Oh!" video shares similarities with its Korean counterpart, however, instead of being a High School oriented video, the video is shot as if the girls have now entered College, implying their growth as artists and women. The video begins with the camera panning through their College dorm, all of the members are seen reading, except for Jessica who is playing the Ukulele, Hyoyeon and Seohyun who are playing Rock-paper-scissors. The camera then focuses on a cheerleading jacket with "Girls' Generation" written on it, as well as a football helmet with "GG" written on the side and a decorated cake with "Oh!" written in decorative writing. It then cuts to Tiffany, who says "Go!" and the girls quickly file out into a red-colored changing room where they begin to sing and dance. The video cuts between this and a stadium setting where the group perform as cheerleaders, as well as solo shots of each of the individual members dressed in their cheerleading uniforms. The video ends with the girls entering back into their dorm, taking off their blue cheer jackets. Taeyeon walks towards the camera with her jacket and puts the jacket over it. The final scene is the girls' empty dorm with the camera focusing on a picture on the wall of the group.

The single managed to reach the top spot on Billboard Japan's Hot 100 and Hot Single Sales. However, fairing less well on radio, with the single only peaking at #27 on Top Airplay chart, and #38 on the Adult Contemporary Airplay chart.
